[R-pkg-devel] R CMD check crash for Ubuntu 14.04 R-3.2.1 only

[Dirk Eddelbuettel]

Charles,

I took a look based on your tar ball.  When I use the normal 'loud' setting I
default to for g++ (ie -pedantic -Wall) or clang++ I get more than a page
full of errors.  I just tried it using the UBSAN-via-clang instrumented R I
provide via a docker container (and for which I showed usage during the
'rocker: Docker on R' tutorial preceding useR! -- slides now on my
presentation page).  It also does not segfault, but it shows a test
difference:

  Running ‘bar.R’
    Comparing ‘bar.Rout’ to ‘bar.Rout.save’ ...8d7
    <
    51,54c50,53
    < [1,]    0    1    0    1    0    0
    < [2,]    0    1    1    0    0    0
    < [3,]    0    1    0    0    1    0
    < [4,]    0    1    0    0    0    1

    > [1,]    0    1    0    0    0    1
    > [2,]    0    1    0    0    1    0
    > [3,]    0    1    0    1    0    0
    > [4,]    0    1    1    0    0    0
      Running ‘bug2.R’
        Comparing ‘bug2.Rout’ to ‘bug2.Rout.save’ ...8d7
        <

(You also seem to consistently differ in one newline which is just a nuisance
and not an error,)

So no free lunch yet.  I fear you may have to minimize the package somewhat
to hopefully arrive at minimally reproducible example.  So far you seem to
have a Heisenbug (https://en.wikipedia.org/wiki/Heisenbug)

Sorry I cannot offer more help.

Dirk
